Single Channel Vibrating Wire Datalogger
MAS-FD01 single-channel vibrating wire acquisition module is a kind of rock and soil in-situ monitoring instrument, which is suitable for signal frequency calculation and temperature acquisition of vibrating wire sensor output. Can be used for dam, bridge, dam, traffic and municipal engineering and high slope engineering stress, strain, deformation, seepage pressure and other physical monitoring and safety and stability analysis. The module is suitable for the data acquisition and long-distance transmission of the distributed measuring point vibrating wire sensor, converts the analog signal into digital signal, and uses the general standard RS485 protocol to transmit the long-distance to the remote end of the system integration, which can be applied in many fields.
Overview
The single-channel vibrating wire acquisition module is used for vibrating wire sensors. The acquisition module sends a frequency sweep excitation signal through the controller to excite the steel string oscillation of the sensor, and the steel string oscillation generates an induced electromotive force. The changing electromotive force signal is processed by the acquisition circuit and finally converted into a digital signal output. The output digital signal includes frequency and temperature information.
Characteristic:
- Exquisite appearance, light weight, easy to carry and easy to install;
- Suitable for data acquisition and long-distance transmission of distributed measuring point vibrating wire sensors;
- Using the latest 32-bit microprocessor to build ultra-high-performance hardware environment to ensure data accuracy, stability and reliability;
- Low power consumption, superior performance, high degree of integration, strong anti-interference ability, waterproof, shockproof, long service life;
Application scenarios:
- Strain monitoring of subway construction;
- Goaf deformation monitoring;
- Bridge and tunnel stress monitoring;
- Water conservancy dam seepage pressure monitoring;
